Sydney: Australian Test `debutant` George Bailey has hailed coach and `cricket nuffy` Darren Lehmann`s random history Tests for keeping the Australian team grounded and constantly learning.

The captain of Australia`s Twenty20 team is no stranger to cricket theories, but reveals that his first two months in the Test change room have been `fascinating` as Lehmann, already revered for his ability to united his charges, had adopted some quirky methods.

According to News.com.au, Bailey said that for all the jovial nature that he puts across, Lehmann is a real student of the game and is `pretty hard` on them about the history of the game, adding that he has caught a few players out over facts like reciting their Test number and who played before them and after them.

Bailey further said that quite often during the game, Lehmann would get a player to give a 3-4 minute spiel about a past player who might have done well at a particular ground or whose name has popped up during the week, adding that he (Bailey) finds Lehmann`s nature in this case very interesting.

Bailey also lauded another new mentor in skipper Michael Clarke , saying that he believes that Clarke is far and away the best captain he has ever played under in terms of driving a game forward and never letting an ideal moment go, adding that he is always tinkering with the field, or the bowling plans while keeping it simple for the bowlers.
